What dissapointed me was the lack of game modes in MP, and the
other game modes what? Only objectives is bad.

Here are my game mode porpouses:

Capture the flag: Capture the enemy's flag. The flag is in the
other side of the map. Max players per team: 6. The team that
reaches the capture limit wins. Capture limit 3.

Domination: Capture the command post to earn points. max players
per team: 8. The Team that Reaches point limit wins. Point limit
100.

King of the hill: Humans Maintain position in a place wile the
necromorphs try to capture it. The humans win when the time limit
is reached. Necromorphs win when they capture the Hill. Max players
per team: 4

Search and Destroy: Humans must destroy the marker that
maintains the necromorphs in feet.
